printed text and pattern are clear and legible.
c) The voltage adjustment range of X-ray tube is 40kV~125kV, which can be adjusted
in different steps, at the increment of 1kV per step.
d) The adjustment range of the current time product is 0.4mAs~200mAs, which can be
adjusted in steps and changed by R′10.
e) On the portable X-ray unit, set the X-ray tube voltage to 100kV, and the current time
product to 20mAs. Place an X-ray quality detector in front of the portable X-ray unit at
1 meter away from the tube focus. Use the exposure hand switch to start the X-ray
exposure. The errors between: the voltage value and the current time product value
of the X-ray tube detected by the X-ray quality detector, and the corresponding
indication values shall comply with the requirements of 1.9 ESSENTIAL
PERFORMANCE in the Manual.
【Caution】: It is recommend that the quality control inspection as described in
step e) above shall be performed at least once a year, or regular quality control testing
of X-ray diagnostic equipment shall be performed in accordance with local laws and
regulations.
f) If step e) fails to comply with the relevant essential performance requirements,
please contact SIUI immediately, and SIUI’s qualified engineers are available for
service.
g) The items packed in the package carton shall match the items listed in the packing
list in terms of models and quantity.
The device, accessories and accompanying documents in the carton shall be enclosed
or padded with film covers and shock-proof materials respectively, ensuring that the
device configuration is complete and safe for transport.
8.6 Cleaning and disinfection
If cleaning the case, portable X-ray machine control panel, and the display enclosure is
necessary, DO NOT use organic solvents and corrosive cleaning liquids for cleaning.
When cleaning, make sure the device is powered off, and prevent water or cleaning
liquids from entering the device, otherwise it might cause device damage.
